| Abstract: | Base on the figure similarity of the compressors and the regular pattern of the location changed, this paper put forward two - step curve fitting method for a centrifugal compressor. It was applied to the fitting of characteristic curve for rev changed while the inlet condition remaining unchanged. The principle is simple, the method is practical and the precision is very high. In this paper, it is proved by the example, as well as illustrate the important question. |
